We receive a Rooter about 15 -18 weeks old from a friend after he settled in he started to attack my wife and I . The chickens free range all day. It does not mater where we are at he will attack. Especially when we walk away from the flock. You really have to keep an eye on him and carry a stick to keep him off. We are new to chickens will he grow out of this or is this going to continue to get worse. Thanks for the Info.
